Continuous spin gravity yields GW time-delay deviations of order ρ_g/ω from GR predictions for frequencies above ρ_g, with damping below, enabling sensitivity to spin scales ~10^{-14} eV at ground interferometers and ~10^{-24} eV at PTAs.
NE2025 refits the thick disk, thin disk, and spiral arms of the NE2001 model and adds refined clumps, delivering 20 times better median pulsar distance accuracy and 100 percent better scattering predictions than NE2001.
uGMRT ranks as the best current instrument for cyclic spectroscopy of pulsars, with the 80-300 MHz band optimal for most of the 312 sources examined.
PCA analysis of NANOGrav data recovers known pulse shape changes tied to timing events in pulsars like J1713+0747 and identifies new candidates and a recurrence in PSR B1937+21.
Forecasts show that adding FAST/SKA upper or lower limits on scalar-induced GWs to CMB+BAO data shifts the scalar spectral index ns by several sigma in LambdaCDM+r and extended models, offering a potential detection indicator.
